Study Notes
Organelles Identification
- Nucleus: Controls cell activities and genetic information.
- Lysosome: Contains digestive enzymes for waste breakdown.
- Centriole: Involved in cell division, aids in spindle fiber formation.
- Cytoplasm: Semi-fluid medium for cellular processes, facilitates metabolism.
- Cell membrane: Protective lipid bilayer, regulates substance exchange.
- Mitochondria: Known as the "powerhouse" of the cell, generates energy.
Plant Cell Organelles
- Vacuole: Storage structure for fluids, food, and waste materials.
- Chloroplast: Site of photosynthesis, converts sunlight into chemical energy (ATP, NADPH).
- Cell membrane: Similar function as in animal cells, protects and facilitates transport.
- Golgi apparatus: Modifies, sorts, and packages proteins from the endoplasmic reticulum.
- Endoplasmic reticulum: Synthesizes proteins and lipids, has rough (with ribosomes) and smooth (without ribosomes) regions.
- Cell wall: Provides structure and support in plants, fungi, and some bacteria.
Functions of Key Organelles
- Nucleus: Regulates cellular functions, stores DNA.
- Ribosome: Synthesizes proteins from messenger RNA.
- Endoplasmic reticulum: Processes and transports proteins and lipids.
- Golgi apparatus: An integral hub for protein modification and delivery.
Additional Functions
- Vacuoles: Maintain osmotic balance and store essential compounds.
- Lysosomes: Digest cellular debris and foreign invaders.
- Mitochondria: Break down nutrients to produce adenosine triphosphate (ATP).
- Cell membrane: Determines cell's permeability and communication with the environment.
More Organelles Insights
- Cytoplasm: Site for glycolysis and general metabolic activities, contains dissolved macromolecules.
- Chloroplasts: Contains chlorophyll for photosynthesis, crucial for plant energy conversion.
- Cell wall: Offers rigidity and defense against mechanical stress and pathogen invasion.
- Centrioles: Organize microtubules during cell division, critical for proper chromosome segregation.
